CPT® Code 63746

The CPT® Code 63746 refers to the procedure involving the complete removal of an entire lumbosubarachnoid shunt system without any replacement. This procedure is typically indicated when complications arise from the shunt, such as obstruction or infection, necessitating its removal. Unlike other procedures where the shunt may be revised, irrigated, or replaced, this specific code denotes the total extraction of the shunt system. The removal process involves making an incision in the skin over the lumbar spine, followed by careful dissection of the overlying soft tissues to expose the shunt catheter. The procedure requires the cutting of any anchoring sutures that may be securing the shunt in place, allowing for its removal from the spinal canal. Additionally, the subcutaneous tunnel that houses the shunt is opened, and the shunt is meticulously dissected free from this tunnel, culminating in the removal of the terminal end of the shunt. This comprehensive approach ensures that the entire system is effectively extracted, addressing the underlying issues that prompted the need for removal.
